I keep getting calls from this number and I don't know who it is or what they want.

I get 3 - 4 calls from this number per day looking for someone that does not live here. Even after telling them that she does not live here they keep calling.

612-729-5607 is Comenity Bank. They start  calling 8:00 AM  to almost 10:00 PM. I told them that calling up to 15 times a day is called harassment I do not want them calling my phone number again and I told them do not call my number again that many times a day. I owed them $60. There paid I'm done with them.

received 14 calls in 4 days

I think World Financial Bank is affiliated with Fingerhut.
